Spectral properties of Eu(III) compound with antibacterial agent ciprofloxacin (cfqH). Crystal structure of [Eu(cfqH)(cfq)(H2O)4]Cl2·4.55H2O

Compounds of Antibacterial Agent Ciprofloxacin and Magnesium – Crystal Structures and Molecular Modeling Calculations

“…It has been shown before that weakly bonded lattice water molecules could easily be lost from metal-quinolone complexes already at room temperature. [23][24][25][26][27] The polymeric 2D square grid complex [Mg(cf) 2 ]·2.5H 2 O was isolated in our lab by hydrothermal reaction at neutral conditions (pH = 7) [13] but also earlier in the labs of a Chinese group at basic conditions (pH = 11).…”

Mononuclear metal complexes with ciprofloxacin: Synthesis, characterization and DNA-binding properties

“…In the literature, diverse transition metal complexes of ciprofloxacin have been structurally characterized. More specifically, the crystal structures of the binary ciprofloxacin complexes with Cu(II) [6,7] and Cd(II) [8] and mixed-ligands ciprofloxacin complexes with Mn(II), Cd(II), Co(II), Zn(II), Ca(II) [9], Fe(III) [10], Cu(II) [11] and Ag(I) [12], where ciprofloxacin is in the neutral form are reported, as well as the crystal structures of the binary ciprofloxacinato complexes with Co(II), Zn(II) [8,9], V(IV)O 2+ [13], Mg(II), Mn(II), Cd(II) [9] and Eu(III) [14] and mixed-ligands complexes with Ba(II) and Sr(II) [9] with ciprofloxacin on the deprotonated mode. No binary complexes of ciprofloxacin with Mn 2+ , Fe 3+ , Ni 2+ and MoO 2þ 2 have been reported yet, although their role as elements of biological interest is well known [15][16][17][18][19].…”

“…A band at 1655.11 cm -1 was for symmetric stretching of the carbonyl group υ C=O of the pyridone moiety. In contrast, the use of Raman Spectroscopy to quantify the presence of fluorine substituent was clearly suspected [29][30][31][32][33] (Table 2 a ).…”
